“The sacred mountain of the northern Thracians (the Daci or Getae). Cf. NM Gugu (Romania), NP Goga, also gogă ‘a ghost, a phantom’ = Alb. gogë etc. Probably archaic Preie. root *K-K-, *G-K- ‘to swell, to inflate; big, make big’. The Romanian mountain Gugu cannot be held as a direct heir of the ancient form, but as a similar, etymologically related place-name. There are no archaeological proofs that Mt. Gugu may directly continue the ancient form.”
